Suggestions for a portable mount?

This will be my first fishfinder but planning to use it on a rental boat (18-20' length) so I can't drill in a mount. Is there a portable transom mount that anyone can recommend?

I just purchased the 300C along with the portable kit (See Attached) Garmin sells and this will make your unit 100% portable. I fish the Quabbin and also use it on my kayak and could not be happier with this unit/kit!

The manual says this device is "rated" at 1 amp. I wasn't sure whether that meant it always draws that much power, or if the power supply should be able to supply that much for peak power draw, so I took my DC ammeter to the lake this week to check it out.

What I observed is that in shallow water, the 300c draws about 0.85 amps at 12v. In deeper water (50+ ft) the power draw seemed to increase slightly to 0.92 amps at 12v.

So, to leave a little bit of wiggle room, the 1 amp rating appears to be a good estimate of the steady power draw for the Garmin Echo 300c. This also makes the battery duration calculation very simple. For a given battery capacity given in amp/hours, the echo 300c should run approximately the same number of hours. For instance, a 4.5 amp/hour (or 4500 milli-Amp/hours since 1 Ah = 1000 mAh) battery pack would run the fish finder for about 4.5 hours on a full charge.

It is worth mentioning that deep discharge recommendations vary by battery chemistry. Some battery types may be damaged unless they retain some minimum percentage of their charge capacity. For instance, if a rechargeable 12v lithium battery pack with an 9000 mAh (i.e. 9 Ah) capacity recommends a minimum 1/3 charge, the actual time limit would be 6 hours (2/3 * 9 Ah) for the echo 300c.

It is also worth mentioning that a multi-cell battery pack (like alkaline AA batteries), with the cells in series, has a total charge capacity equal to that of each one of the cells. So, a battery pack made up of 8 individual alkaline AA batteries (typically 2500-3000 mAh) might run the echo 300c between 2 and 3 hours.

Yes, the water temperature is measured at the transducer (surface).

To understand how this information translates into water temperature at various depths, search the web for "water temperature stratification."

If you want to know the temperature of the water at some depth below the surface, you also need something like a "ProCatch Plus", a "ClineFinder", or some other product that has a temperature sensor you can lower into the water to the depth where you want to measure the temperature (and usually some other stuff like clarity or oxygenation).
